Toward a comparative history of medical genetics as a medical specialty in North America.

Much of what has been written about the history of medical genetics in North America has focused on physician involvement in eugenics and the transition from heredity counseling to genetic counseling in the United States. What are typically missing in these accounts are details concerning the formation of a new medical specialty, i.e., medical genetics, and Canada's involvement in specialty formation. Accordingly, this paper begins to fill in gaps by investigating, on the one hand, the history of American and Canadian geneticists working together to support the creation of examining and teaching positions in human genetics in North American medical schools and, on the other, working independently of one another to monitor the rate and direction of workloads and patient access to local genetic counseling and laboratory services and, subsequently, achieve recognition for medical genetics as a medical specialty at the national level.

On shaping expectations of "new normals" for living in a post-COVID-19 world.

I begin with my impressions of a narrative of redemption that is caught up in the formation of new environmental, social, and political aspirations for the aftermath of the COVID-19 pandemic. I then reflect on, first, pre-pandemic scholarship on "biosecurity" and, second, taking up a variation of the syndemic approach to understanding the COVID-19 pandemic. I end by arguing that we should not expect to live with "new normals" for living in a post-COVID-19 world that leaves intact "old normals" that have historically contributed to the rise of anthropogenic environmental harms and inegalitarian social arrangements in the world today.

Synthesis, convergence, and differences in the entangled histories of cytogenetics in medicine: A comparative study of Canada and Mexico.

Most historians of science and medicine agree that medical interest in genetics intensified after 1930, and interest in the relationship of radiation damage and genetics continued and expanded after World War II. Moreover, they maintain that the synthesis and convergence of human genetics and cytological techniques in European centers resulted in their dissemination to centers in the United States, resulting in a new field of expertise focused on medicine and clinical research, known as cytogenetics. In this article, we broaden the scope of the inquiry by showing how the early histories of cytogenetics in Canada and Mexico unfolded against strikingly different backgrounds in clinical research and the delivery of health care. We thus argue that the field of cytogenetics did not emerge in a straightforward manner and develop in the same way in all countries. The article provides a brief background to the history of human cytogenetics, and then outlines key developments related to the early adoption of cytogenetics in Canada and Mexico. Conclusions are then drawn using comparisons of the different ways in which local determinants affected adoption. We then propose directions for future study focused on the ways in which circuits of practices, collaborative research, and transfers of knowledge have shaped how cytogenetics has come to be organised in medicine around the world.

Looking Back on the Future of Genetic Counselling in Canada.

This article focuses on how occupational roles and working relationships have changed over time for individuals involved in genetic counselling in Canada. It begins with a review of the stages of consensus that were reached about a role for geneticists and genetic counselling in clinical settings and, second, the formation of medical genetics as a service specialism. Interviews conducted by the author and survey data collected by the Canadian Association of Genetic Counsellors/L'Association Canadienne des Conseillers en Génétique are then used to examine role divarication in genetic counselling and the boundary realignment in inter-professional relations among physician and non-physician genetic counsellors. This leads, in a final step, to a summary of what the research shows about the changing face of genetic counselling in Canada and directions for future investigation.

Tracing the shifting sands of 'medical genetics': what's in a name?

This paper focuses on the structural development of institution-based interest in genetics in Anglo-North American medicine after 1930 concomitantly with an analysis of the changes through which ideas about heredity and the hereditary transmission of diseases in families have passed. It maintains that the unfolding relationship between medicine and genetics can best be understood against the background of the shift in emphasis in conceptualisations of recurring patterns of disease in families from 'biological relatedness' to 'related to chromosomes and genes'. The paper begins with brief considerations of the historical confluences of, first, heredity and medicine and, second, genetics and medicine which, in a third section, leads to a discussion about a uniquely 'genetics-based approach' to medicine in the second half of the twentieth century.

Ideas about heredity, genetics, and 'medical genetics' in Britain, 1900-1982.

The aim of this paper is to understand how evolving ideas about heredity and genetics influenced new medical interests and practices and, eventually, the formation of 'medical genetics' as a medical specialism in Britain. I begin the paper by highlighting the social and institutional changes through which these ideas passed. I argue that, with time, there was a decisive convergence in thought that combined ideas about the familial aspects of heredity and the health needs of populations with an omnibus 'genetic' approach to health and illness that focused on the structures and activities of chromosomes and genes in individuals. I show how this convergence in thought was spurred on, first, by innovations in genetic science and technology in the years after 1960, and, second, by negotiated protocols and standards of medical practice worked out by bodies such as the relevant royal colleges, the linked associations and societies for medical professionals, affected training and research authorities, and the state. The notion of 'medical genetics' in Britain consequently gained a semblance of unanimity over its basic reference points and arrived at a meaning directly tributary to current acceptance of the term in the context of a medical specialism.
